[0037] Specifically, the dust hopper 14 is used to collect dust and impurities inside the dustproof shell 4, the support feet 17 ensure the stability and safety of the combustion tower 1, the controller 22 is used to control the operation of the entire system, including the start and stop and speed adjustment of the fan 16, the air compressor 6 provides the system with necessary compressed air, the maintenance door 20 is convenient for the staff to inspect and maintain the equipment, the handle 21 allows the staff to easily open and close the maintenance door 20, the water inlet pipe 25 is responsible for transporting water to the inside of the water washing tower 19, the water storage tank 23 stores enough water for the water washing tower 19, the placement of the ceramic plate 24 can make the gas react fully, and can also protect the inner wall of the combustion tower 1 from erosion by high temperature and chemicals, and the inner wall of the gas supply pipe 3 is fixedly connected with a heating pipe 26, which can preheat the gas entering the combustion tower 1.

[0038] Working principle: When the exhaust gas enters, it is first accelerated by the fan 16 and enters the dustproof shell 4 through the air inlet pipe 15. When the exhaust gas passes through the dust bag 12, the dust and particulate matter in the exhaust gas are adsorbed on the surface of the dust bag 12. The exhaust gas with removed particulate matter enters the combustion tower 1 through the air pipe 3 for combustion treatment. When the surface of the dust bag 12 adsorbs a lot of particulate matter and the filtering effect is not enough, the air compressor 6 is started. The compressed air generated by the air compressor 6 is blown to the inner wall of the dust bag 12 through the compression pipe 7, the branch pipe 8 and the nozzle 9, so that the particulate matter on the outer wall of the dust bag 12 falls off and falls into the dust hopper 14. This can protect the equipment, optimize the treatment effect, will not affect the next step of treatment, and can also reduce the wear of the inner wall of the equipment caused by dust and particulate matter during the flow process;

[0039] When the waste gas treated by the water scrubber 19 is discharged, a large number of small droplets are mixed in the treated gas. When the gas flows to the corrugated plate 203, due to the inertial impact of the gas, the droplets impact the surface of the corrugated plate 203, and the droplets gather. When the gravity of the gathered droplets exceeds the upward force of the gas, the droplets will separate and fall from the corrugated plate 203. The droplets that are not removed are captured by the same action at the next turning point. After repeated actions, the demisting efficiency is greatly improved. Finally, the dry gas is discharged after being filtered by the activated carbon 206. There is still a certain amount of tiny droplets in the waste gas treated by the water scrubbing process. There will be pollutants dissolved in water in the droplets. If directly discharged, it will still cause pollution to the atmospheric environment. Demisting can reduce the emission of harmful substances in the waste gas.

[0040] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements on some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
